Dear lammps users,
Could you tell me what distance units LAMMPS uses in pair_style and pair_coeff?
For example, I use the following command
pair_style lj/cut 5.0
pair_coeff * * 1.0 1.0
But there are two kinds of distance units: box units, and lattice units.
Which units is used for pair_style/coeff command?
In region command, we add “box units” following the command to use box units.
Therefore, should I make a command such as “pair_style lj/cut 5.0 box unuits”?
